If we're using an IN endpoint, the DMA direction
is DMA_FROM_DEVICE, rather than DMA_TO_DEVICE.

Greg, I will be sending this to the 3.3 merge window,
it's already on my branch, that's why I'm Ccing stable,
so this should be applied only to 3.2. If there's still
time to apply this on 3.2, please take the patch in on
top of my latest pull request and I can drop it from
my pull for -next.
